Sept. 22 (Bloomberg) -- The world’s wealthiest people lost
a combined $9.6 billion this week, according to the Bloomberg
Billionaires Index, which has expanded to 100 names.

The two richest newcomers are women. Dirce Navarro de
Camargo, Brazil’s third-richest person, controls Sao Paulo-based
conglomerate Camargo Correa SA. Elaine Marshall, a 70-year-old
Dallas resident, controls almost 15 percent of Koch Industries
Inc., the second-largest closely held company in the U.S.

The two grandmothers rank 62nd and 67th, respectively, on
the index, and command $13 billion fortunes. Both women
inherited their stakes following the death of their husbands.

“Individuals who come into their wealth through windfall,
such as inheritance or the lottery, tend to have lower risk
tolerance than the self-made wealthy, who generally have
repeatedly taken significant risks to achieve their wealth,”
said Daniel Egan, a behavioral finance specialist for Barclays
Wealth and Investment Management, in an interview from his New
York office.

Stocks fell in the U.S. and Europe this week. Global equity
funds lured the largest weekly inflows this year, Citigroup Inc.
said, after the U.S. Federal Reserve unveiled another round of
quantitative easing and the European Central Bank pledged to buy
bonds to contain the debt crisis. European policy makers will
unveil a financial bailout program for Spain as early as next
week.

The Standard & Poor’s 500 Index lost less than 0.4 percent
during the week to close at 1460.15 in New York. The Stoxx
Europe 600 Index fell less than 0.1 percent, closing at 275.78.

Slim, Kamprad

The collective wealth of the index is $1.9 trillion. The
group has gained a combined $214.5 billion this year.

Mexican telecommunications magnate Carlos Slim, 72, remains
the richest person in the world, with a fortune of $74.5
billion, down $1.4 billion for the week. Second is Microsoft
Corp. co-founder Bill Gates, 56, with $64.8 billion.

Ingvar Kamprad, the 86-year-old founder and owner of IKEA,
the world’s largest furniture retailer, ranks fifth on the index
with a $43.5 billion fortune.

China’s Richest

Zong Qinghou was revealed to be China’s richest man after
disclosing that his stake in Hangzhou Wahaha Group Co., the
country’s third-largest beverage maker, is more than double
previous estimates. Zong, who heads the closely held company and
is a chain-smoking member of the Chinese legislature, ranks No.
24 globally with a net worth of $22.1 billion.

Tadashi Yanai is Japan’s richest man. The billionaire
controls about 46 percent of Fast Retailing Co., the largest
clothing retailer in Asia and parent of the Uniqlo casual wear
chain. The 62-year-old ranks 80th in the world with a net worth
of $11.6 billion.

Richest Seaman

Leonid Mikhelson, the billionaire who controls OAO Novatek,
Russia’s largest private gas producer, has been closing the net-worth gap with Alisher Usmanov, Russia’s richest man. Mikhelson
is now $1.6 billion behind Usmanov, who controls an $18.7
billion fortune with interests in mining, technology and
telecommunications.

Bernard Arnault, France’s richest man, is worth $24.4
billion. The chief executive officer of LVMH Moet Hennessy Louis
Vuitton SA, the world’s largest luxury-goods company, filed an
application to become a Belgian national earlier this month. The
billionaire promised he would continue to pay taxes in France,
countering reports he wants to avoid taxes.

John Fredriksen, the world’s richest seaman, ranks 63th on
the index. The 68-year-old Norwegian shipping magnate’s most
valuable asset is offshore drilling company Seadrill Ltd. He has
a $13.3 billion net worth.

Commodity Startups

The fortune of Eike Batista, Brazil’s richest man, has
slumped since February. OGX Petroleo & Gas Participacoes SA, his
flagship oil company, reduced its production targets in June,
leading to a sell off across his empire of publicly traded
commodity startups.

The billionaire is in talks to sell his shipbuilding
business, OSX Brasil SA, to Sete Brasil Participacoes SA in
exchange for a stake in the startup oil-rig operator, according
to two people with direct knowledge of the matter.

Mark Zuckerberg, the 28-year-old co-founder of Facebook
Inc., the world’s largest social-networking company, has fallen
to the 79th in the world. Zuckerberg has lost $7.6 billion since
Facebook sold shares in an initial public offering on May 17.
His fortune is now $11.7 billion.

No. 100 on the list is Samsung Electronics Co. chairman Lee
Kun Hee of South Korea. He is worth $10 billion.

The Bloomberg Billionaires Index takes measure of the
world’s wealthiest people based on market and economic changes
and Bloomberg News reporting. Each net worth figure is updated
every business day at 5:30 p.m. in New York. The valuations are
listed in U.S. dollars.

The expanded list was published with the release of
billionaires profile pages in the Bloomberg Professional
service. The profiles feature a transparent analysis of how each
billionaire’s fortune was calculated.
